What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveAs more U.S. states legalize cannabis, marketing from the cannabis industry and news coverage of cannabis have increased. Sources of information on cannabis can influence beliefs about risks and benefits. Yet, little is known about how the use and influence of specific sources of information have changed over time.
methodWe conducted a longitudinal study of 5,053 U.S. adults between 2017 and 2021. Participants were asked about sources of information on cannabis risks and benefits and which sources were most influential using a web-based survey at three different time points (2017, 2020, 2021). We evaluated changes in the use/influence of multiple sources of information from 2017 to 2021 and examined interactions with age, cannabis use, and state cannabis legal status.
resultsThe largest increases in sources of information on cannabis benefits and risks were in the use of health professionals (+5.5% for benefits and +17.4% for risks). The largest declines were in the use of traditional media (television, radio, newspapers) (-12.3% and -11.4%, respectively). The use of cannabis advertisements and dispensaries/other industry sources also significantly increased. Health professionals were the most influential source of information in all three waves regardless of age, cannabis use, or state legal status.
conclusionsParticipants sought information from different sources and increasingly relied on health professionals as a primary source, highlighting the need to train health care providers about cannabis risks and benefits. Although fewer people used traditional media, use of industry sources increased, underscoring the need for accurate cannabis information sources.
